Volkswagen ID.3 Forum

If you adjust your tyre pressures you have to go into settings (Tyres, on the Vehicle screen) and SET. The car then OKs this and SAVES the new pressure if deemed to be within limits.

Most Tyre pressure monitoring systems do not actually measure the tyre pressure but monitor the wheel speeds using the ABS sensor. The system then looks for any mismatch in rotation speed between the wheels indicating that there has been a change in overall circumference and then flags this as a tyre pressure problem.

Really interesting, I didn't know that! Thanks for this!

great reply's many thanks

Silly question probably but does replacing either the alloys or wheel trims count as a modification for insurance purposes?

Alloys maybe - wheeltrims no.

Wheeltrims have no bearing on how the car operates.. alloys might if they were not specific to the iD3 for example...

(all IMHO etc..)

If you do it after delivery then you must declare this.

Declaring alloy wheel doesn't (usually) add anything to you premium so it is well worth telling them.

Back to Alloys, the dealer I went to had a Max available but with the steel wheels (why are alloys not not standard???). I had them put the Loen Alloys on for the same cost as the other Alloys that are factory fitted. Car was delivered in 2 weeks as a result otherwise would have had to wait for 3 months. I have also used tyre pressure sensors with a visual indication of the pressure. Display is windscreen mounted and solar powered. When you have a problem, you know which wheel it is. Have similar on my motorbike.

The cars standard tyre pressure warning system should pick up any discrepancy anyway it shouldn't matter which wheels are fitted?
